Issue has been resolved. The seller in question was willing to work with me, and went above and beyond.
I asked for a rebuild kit for the flippers, $50 value. He, without letting me know, sent more than that, and asked "Fair Enough?"
It certainly is, and was a gesture I greatly appreciate.
There is no longer a need for me to post photos or discuss this further. Please lock or delete this thread.
Thank you.
